Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164154, here are decompositions:

5 + 164149 = 164154
7 + 164147 = 164154
37 + 164117 = 164154
41 + 164113 = 164154
61 + 164093 = 164154
83 + 164071 = 164154
97 + 164057 = 164154
103 + 164051 = 164154

Showing the first eight; more decompositions exist.
